The panel data estimation technique was used to identify the determinants of total factor productivity. At maximum production efficiency, an entity cannot produce any additional units without drastically altering its production process. Analysis of production efficiency also involves a close look at costs. As such, economies and many individual entities aim to find a good balance between the use of resources, therate of production,and the quality of the goods being produced without necessarily maxing out production at full capacity. Your actual output is how much you currently manufacture in terms of the unit you have chosen, such as per pound of rubber.
